AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help.

You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

The Network Lifecycle Management (NLM) organization is responsible for scaling and maintaining Amazon's global network capacity. Within NLM, the Cabling Services team owns the planning, ordering, and fulfillment of network cabling projects. This includes building software to ensure predictable, on-time delivery of materials to deliver network capacity.

You will have the autonomy to define your own direction, shape technical solutions, and drive meaningful outcomes across the cabling lifecycle.

We are a collaborative team that values continuous learning, technical curiosity, and a culture of shared growth. We run regular knowledge-sharing sessions and offer opportunities to explore emerging technologies.
